Cisco Aci: Zero to Hero: A Comprehensive Guide to Cisco Aci Design, Implementation, Operation, and Troubleshooting (Paperback)

It doesn't matter if you are completely new to Cisco ACI or you already have some experience with the technology, this book will guide you through the whole implementation lifecycle and provide you with a comprehensive toolset to become confident in any ACI-related task.

In the beginning, it's very important to build strong fundamental knowledge about Cisco ACI components. We'll go through underlay networking based on Nexus 9000 switches and describe the APIC controller cluster acting as the management plane of ACI. By building Access Policies, you'll see how to optimally connect servers, storage, routers, switches, or L4-L7 service devices to ACI. Then we'll properly design and implement Logical Application Policies. You will understand all the fabric forwarding behaviour when using different ACI settings and architectures while getting a toolset on how to verify and troubleshoot eventual problems.

This book also covers external L2 and L3 connectivity in ACI, more advanced features like integration with virtualization hypervisors and Kubernetes, service chaining of L4-L7 devices using Service Graphs, or practical approach to using REST API automation based on Python and Ansible/Terraform.

Cisco ACI: Zero to Hero can additionally be used as a valuable source of theoretical and practical knowledge for all candidates preparing for CCIE DC v3.0 Written or Lab exams.

What You'll Learn

- Understand network evolution and Cisco ACI components

- Underlay ACI networking based on Nexus 9000 switches, APIC controllers, and Application Policy Model

- Integrate ACI with virtualization hypervisors and Kubernetes

- Dynamically and seamlessly include L4-L7 service devices in communication between ACI endpoints

- Build ACI Anywhere - ACI Multi-Tier, Stretched Fabric, Multi-POD, Multi-Site and Remote Leaf

- Utilize ACI REST API with Python, related Cobra SDK, Ansible or Terraform, to develop your automation and scripts on top of the ACI platform

Who This Book Is For

Network engineers, architects, network developers, administrators or NOC technicians.

無論您是對 Cisco ACI 完全陌生，還是已經對這項技術有一些經驗，本書都將引導您完成整個實施生命週期，並為您提供全面的工具組，使您能夠在任何與 ACI 相關的任務中充滿信心。

首先，建立關於 Cisco ACI 組件的堅實基礎知識非常重要。我們將介紹基於 Nexus 9000 交換機的底層網絡，並描述作為 ACI 管理平面的 APIC 控制器集群。通過建立存取策略，您將了解如何將服務器、存儲、路由器、交換機或 L4-L7 服務設備與 ACI 最佳地連接起來。然後，我們將正確地設計和實施邏輯應用策略。在使用不同的 ACI 設置和架構時，您將了解所有的布線轉發行為，同時獲得一套工具，用於驗證和排除可能出現的問題。

本書還涵蓋了 ACI 中的外部 L2 和 L3 連接，以及更高級的功能，例如與虛擬化超級管理員和 Kubernetes 的集成，使用服務圖形進行 L4-L7 設備的服務鏈接，以及基於 Python 和 Ansible/Terraform 的 REST API 自動化的實際應用方法。

此外，《Cisco ACI: Zero to Hero》還可作為準備 CCIE DC v3.0 寫作或實驗考試的所有考生的理論和實踐知識的寶貴資源。

您將學到什麼：

- 了解網絡演進和 Cisco ACI 組件
- 基於 Nexus 9000 交換機、APIC 控制器和應用策略模型的 ACI 底層網絡
- 將 ACI 與虛擬化超級管理員和 Kubernetes 集成
- 在 ACI 端點之間的通信中動態無縫地包含 L4-L7 服務設備
- 構建 ACI Anywhere - ACI 多層、擴展布線、多 POD、多站點和遠端 Leaf
- 利用 Python、相關的 Cobra SDK、Ansible 或 Terraform 使用 ACI REST API，開發您的自動化和腳本，建立在 ACI 平台之上

適合閱讀對象：

網絡工程師、架構師、網絡開發人員、管理員或 NOC 技術人員。

Jan Janovic, 2x CCIE No. 55858 (R&SDC) and Cisco Certified Instructor (CCSI #35493), is an IT enthusiast with 10+ years of experience with network design, implementation and support for customers from a wide variety of industry sectors. During the last years, he has focused on data center networking, mainly, but not limited to solutions based on Cisco Nexus platforms - traditional vPC architectures, VXLAN BGP EVPN network fabrics and Cisco ACI Software-Defined Networking. All with an emphasis on mutual technology integration, automation and analytic tools. Another significant part of his job is the delivery of professional training for customers all around Europe.

During his university studies, he led a group of students to the successful development of the world's first Open-Source EIGRP implementation for the Quagga Linux package (currently under the name FRRouting). He also contributed to OSPF features there.

His technical focus additionally expands to public cloud topics connected with the design and deployment of AWS and Azure solutions.
